It is permissible to run the trap up to 5 ft. away from the furnace to
an area with the required trap clearance provided the following
steps and conditions are followed.

Remote Trap Installation Specific Steps
1. Glue included 90 CPVC elbows to shortest two CPVC
Tubes (A and B) or replace with two field supplied 1/2-in.
CPVC tubes of the desired length (5 ft. or less) to extend
out of the cabinet.
2. Remove adhesive backing from the Collar Gasket and apply
it to the rear side of the Collar Plate.
3. Place Collar Plate over condensate drain knockout and
fasten to cabinet with six (6) of the sheet metal screws.
4. Install elbow and tube assemblies by routing tubes through
collar plate and inserting the ends into the rubber elbows
previously installed on the collector box. Ensure elbows are
pointed toward desired trap location before tightening the
clamps.
5. Torque the clamps to hand- -tight (15 lb- -in.). Over
tightening hose clamps may crack plastic components
which may result in water leaks and possibly water damage.
6. Attach the field supplied 1/2-in. CPVC tubing for the
remote run to the 90 elbows that extend past the casing.
Run the two drain lines up to 5 ft away from where they
exit the furnace casing to reach the remote trap location. All
condensate drain line joints must be glued with CPVC glue.
7. Use provided tubes (Tube E) to extend into the main body
of the trap and CPVC elbows MUST touch the top of the
PVC tube of the main trap.

8. Mount included Upflow Bracket to structure ensuring
condensate drain is sloped 1/4-in. per foot and that the
CPVC elbows rest on top of the PVC tube of the main trap
(Fig. 24).
9. Set the Trap Assembly on the arms of the Upflow Bracket
and tighten with the provided bolt and nut. Ensure the
bottom of the large Tee is resting on the bracket (Fig. 18).

Finishing Installation
1. Route the float switch wires through a Plastic Grommet and
then through a knockout to the blower compartment. Adjust
Plastic Grommet so that it seals the cabinet.
2. Using wire nuts, make connection between Float Switch
and Pigtail Harness Assembly. Lastly, join the 2 pin
receptacle from the Pigtail with the 2 pin receptacle that
originates from the control board 12- -pin connector.
Alternate Horizontal Option - - Remote Trap may require
additional field supplied wire to make connection between
float switch and pigtail harness assembly connected to
control board.
3. If the installation is a Direct Vent application, apply silicone
or duct putty around the CPVC tubes passing through the
clearance holes in the Plastic Collar to fully seal the
combustion vestibule.
4. The remaining drain line can be constructed from field sup-
plied 1/2- -in. CPVC or 3/4- -in. PVC pipe, in compliance
with local building codes. A factory- -supplied 1/2- -in.
CPVC to 3/4- -in. PVC adapter is supplied in the loose parts
bag for use as required.
5. Connect additional condensate piping to a code- -approved
drain, or to a condensate pump approved for use with acidic
furnace condensate and compatible with mineral and
vegetable oils, such as canola oil.
6. Allow at least 1/4-in. per foot (20 mm per meter) of slope
down and away from the furnace in horizontal sections of
A190392
drain line.
Installation of Evaporator Coils
When installing the evaporator coil, refer to the allowed installation
configurations (Table 6). Some coils require an 8- -in. tall sheet
metal spacer between the furnace and the coil or some require a
metal shield between the drain pan of the coil and the discharge
flanges of the furnace. This is to protect the composite drain pan of
the evaporator coil. The coil offset adapter kits in the product
accessory list will require an additional field fabricated adapter to
ensure the 8- -in. separation.
FIRE HAZARD
When installing evaporator coils that have composite
(plastic) drain pans and are exposed directly to the furnace
heat exchanger, a sheet metal spacer/transition or drain pan
shield is required.
Failure to protect the coil composite drain pan could result
in fire, personal injury, or death. (Table 6)
Specifications subject to change without notice.
